What type of blood test can help identify kidney function?

BUN (Blood Urea Nitrogen) and creatinine levels are crucial indicators of kidney function. These tests measure the concentration of waste products in the blood that are normally filtered out and excreted by the kidneys. When the kidneys are not functioning properly, the levels of BUN and creatinine can rise, signaling potential issues like kidney disease or dysfunction.

A complete blood count (CBC) mainly provides information about the overall health of the patient, including red and white blood cells, but does not specifically indicate kidney function. The blood glucose test measures the concentration of glucose in the blood and is used to assess diabetes, while liver enzyme tests focus on evaluating liver health, not kidney status. Therefore, the assessment of BUN and creatinine levels is essential for understanding how well the kidneys are working and is the appropriate choice for evaluating kidney function.
